摘要:
An argon purification system comprising an ambient temperature molecular sieve adsorption step, an ambient temperature chemisorption step, and a cryogenic temperature adsorption step, particularly useful with liquefaction of the purified argon.
摘要:
A cryogenic air separation system wherein high pressure oxygen is transition-warmed against both transition-cooling feed air and transition-cooling nitrogen, supplying added reflux for the air separation and enabling column operation at higher pressures without degraded recovery.
摘要:
A method for cleaning and recycling protective atmosphere for a float glass facility wherein contaminated protective atmosphere is cooled, preferably while scrubbing out particulates, compressed, and then purified by passage through a bed comprising water selective and hydrogen sulfide selective adsorbents.
摘要:
A cryogenic rectification system employing a double column and two auxiliary reboilers associated with one or two auxiliary columns wherein both lower purity oxygen and higher purity oxygen is produced.
摘要:
A cryogenic air separation plant or a combined pressure swing adsorption plant and membrane separation plant is integrated with a float glass manufacturing system wherein oxygen from the plant is used for oxy-fuel combustion in the melt furnace and nitrogen from the plant is used as a protective atmosphere in the float glass forming chamber.
